I'm running Ubuntu 15.10, I changed my cursor theme to dmz-black then restarted. It worked, but when I just logout and login cursor theme has changed to default (dmz-white) yet dmz-black theme is working only on Google Chrome.

So I again restarted then again the correct theme appeared then I again logout and login then again cursor theme changed to default (correct theme only working on Chrome).

I changed the theme using many ways

  1. Through Unity Tweak Tool
  2. By editing /usr/share/icons/default/index.theme
  3. By running sudo update-alternatives --config x-cursor-theme
  4. Via Dconf-Editor
  5. By creating .icons/default/index.theme and pasting

    [Icon Theme]
    Inherits=DMZ-Black into index.theme

But none of these methods solved my problem.


  • I have the same problem using Ubuntu Studio. Xfce has a built-in setting for mouse pointers. The standard black pointer works after reboots, but changes at some point I can't define. Then, the pointer will switch between white/black depending on the focused window (e.g. white on panel, black on browser, etc.) – Prototype700 Dec 13 '15 at 15:54

    Possible duplicate of Ubuntu tweak tool - Mouse cursor would not change theme – Martin Thornton Jan 16 '16 at 1:54

Try this one

You must have a hidden directory and a file named index.theme in your user home directory like ~/.icons/default/index.theme

open it with your text editor and replace Inherits with :

[Icon Theme]
Comment=Default Cursor Theme

Then logout and login

If your mouse theme changes per application then

open ccsm > general options and enter your mouse theme name in Default Icon

There is a tool named lxappearance in repo, you can use it to customize your theme with it.

  • Thanks, But It seems not working..thanks in advance for mentioning the app lxappearance – Confidential Jan 17 '16 at 16:38

Are you using a live USB? Live USBs have the OS on them but reset after restart. Try setting up a persistence file when using a USB so you can save the changes

  • i just installed ubuntu using a usb (pen-drive) thats it. i didnt get what u asked – Confidential Dec 13 '15 at 15:06
  • He was asking if you were running Ubuntu from a USB drive or have it fully installed on your hard drive. I can confirm that this happens on a full installation. – Prototype700 Dec 13 '15 at 15:58
  • @Prototype700 thanks..thats right! happens on a full installation. I just re-installed xcursor-themes and dmz-cursor-theme using Synaptic Manager many times..but no answer – Confidential Dec 16 '15 at 21:41
